A few of these aren't correct.

apl"(ι5) ×∘ ι5"

First, the symbol in APL is ⍳, not ι.
Second, this would be an atop (×∘), which is not what you want: what you want is outer product.

In APL (at least Dyalog APL), that's ∘.×.

    (⍳5)∘.×⍳5
1  2  3  4  5
2  4  6  8 10
3  6  9 12 15
4  8 12 16 20
5 10 15 20 25
