Table of n, a(n) for n=1..55.

FORMULA

a(n)=log(mod(A132416(n),10),A132416(n)); d^a(n)=A132416(n) where d is the last digit of A132416(n), d=A132416(n) mod 10.

EXAMPLE

a(10)=2 because A132416(10)=25 the last digit of which is 5 and 5^2=25;

a(11)=5 because A132416(11)=32 the last digit of which is 2 and 2^5=32;

a(13)=3 because A132416(13)=64 the last digit of which is 4 and 4^3=64.

MATHEMATICA

a[n_]:=Log[Mod[A132416[n], 10], A132416[n]]
