Given that there appears to be a minor error in the definition of e3 in the
original post, I'll repeat what I think was intended below:
e3=: 12 13 14 15 16 11 2 3 4 17 10 1 0 5 18 9 8 7 20 6 19 24 23 22 21
f=: 1 2 3 5 8 13 21
e3=: 5 5$ e3
;"1 (e3 e."1 f)} (5 5$<'. '),:<'@ '
NB. or the more complete ...
1j1&#"1 ((e3 e."1 {.f)+e3 e."1 f)}'.','@',:5 5$'X'
