AXMAS , AX two Xmas's trees design.
AX is a "tree" that is already decorated, does not call any other lambda. The ornaments are embedded in the function.
AXMAS is an undecorated one. We can choose our own ornaments array "or". Call AFLAT.
AFLAT , flattens the ornament array, and gives us the versatility to deal with arrays of any shape, size, dimensions, with blanks/null strings, ranges, or other array formulas.
Both designs, randomly, change the display of ornaments every time spreadsheet recalculates, or if we hit F9.
Both lambdas share same concept design, creating a Xmas tree shape, a "triangular" array that can be filled with random values.
A triangular array is like designing a symmetric staircase, it has stairs or steps, and has 2 input parameters "ht", the approximate total height, and "sh", each stair height. Each stair width or depth is by default 1. Knowing these parameters, the function knows how to calculate nr. of steps, exact total height to accommodate nr. of steps and total width footprint of the "staircase".
Both lambdas share same ornament topper (2 parts), and same tree base, (last row) where presents boxes are placed. First variables after LET.

Everybody is free to believe in whatever they consider. Me, I believe in Santa, Excel's Santa. So, the other day, I wrote him a letter. It was a secret wish, but now I am going to disclose it. I've wished for more recursive iterations. Very anxious, when I woke up this morning, I run under my Xmas tree to open the present boxes, hoping that I will find at least "1000 iterations". Instead, look what I found. ?

As I've shared with you, I did not receive anything good from Excel's Santa, but, I've missed a present box, and….what I found inside is amazing.
It's a solution for something that has been bothering me since day one of the new lambda helper functions. The fact that BYROW or BYCOL do not spill arrays, only single values.
Solved it before though, with an "external" function as "accumulator" (latest posts ASCAN's thread). This solution does not need any. Good Excel's Santa after all. ?✌️?

323114=BYROW(B3:F5,LAMBDA(a,SORT(a,,1,1)))
478598#CALC!
564463

7The Solution
8sort ascending "byrow"
9=LET(a,B3:F5,r,ROWS(a),s,SEQUENCE(r),REDUCE(0,s,LAMBDA(v,i,IF(SEQUENCE(i)=i,SORT(INDEX(a,i,),,1,1),v))))
1011234
1157889
1234466Works!!!
13
14unique "byrow"
15same formula, we only have to replace function SORT with UNIQUE
16=LET(a,B3:F5,r,ROWS(a),s,SEQUENCE(r),REDUCE(0,s,LAMBDA(v,i,IF(SEQUENCE(i)=i,UNIQUE(INDEX(a,i,),1),v))))
172314
187859
19643#N/AWorks!!!
20
21this is the construction that works without any other "accumulator", performing calculations "byrow" that can spill.
22 =REDUCE(0,SEQUENCE(ROWS(a)),LAMBDA(v,i,IF(SEQUENCE(i)=i, function(INDEX(a,i,)),v)))
23This is the solution I found in the present box!!!! ✌️✌️
24
25Defining a custom made lambda helper "byrow" that spills (name it AROW),
26needs a lambda as argument that embeds the function that instructs REDUCE what to perform. (like in our examples)
27
28if y(x)=LAMBDA(x,function(x)), then:
29AROW(a,y)=LAMBDA(a,y,LET(r,ROWS(a),s,SEQUENCE(a),REDUCE(0,s,LAMBDA(v,i,IF(SEQUENCE(i)=i,y(INDEX(a,i,)),v)))))
30Calling it =AROW(a,LAMBDA(x,function(x))) will work for any function(x)
31In other words, whatever results y(x) can spill (horizontally) for a single row,
32AROW will do it "byrow", for each row of an array "a"
33
34Ofcourse "y" can represent lambdas with more arguments, will see how to instruct reduce to handle them.

Ornaments "storage" array AO() was not the first lambda argument free function. First was about creating a chessboard ACHESS()
For fun, I found a way to be able to play chess. Other functions on mini-sheet ACHESS, AROTATE (last post AFLIP thread)
Other ideas that can use lambda argument free functions could be shuffling n decks of cards or rolling n dices.
