A256308 Apply the transformation 0 -> 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 0 to the digits of n written in base 8; do not convert back to base 10. 8

COMMENTS

Base 8 variant of A256078 (base 2) and A048379 (base 10). See A256303 - A256307 for bases 3 through 7, A256289 for base 9, and A256298 for the variant where the result is converted back to base 10.

LINKS

Table of n, a(n) for n=0..59.

EXAMPLE

a(8) = 21 because 8 = "10" in base 8 becomes "21".

a(63) = 0 because 63 = "77" in base 8 becomes "00".

MATHEMATICA

Table[FromDigits[IntegerDigits[n, 8]/.{0->1, 1->2, 2->3, 3->4, 4->5, 5->6, 6->7, 7->0}], {n, 0, 60}] (* Harvey P. Dale, Mar 29 2015 *)

PROG

(PARI) A256308(n, b=8)=!n+eval(Strchr(apply(d->(d+1)%b+48, digits(n, b))))
