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.
