Invitation: celebrating 50 years of OEIS, 250000 sequences, and Sloane's 75th, there will be a conference at DIMACS, Rutgers, Oct 9-10 2014.

Hints
(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A112727 a(n) is the least integer m greater than one such that m^n is a palindrome. 0
2, 2, 2, 2, 11 (list; graph; refs; listen; history; text; internal format)
OFFSET

0,1

COMMENTS

There is no further term up to 10^8.

LINKS

Table of n, a(n) for n=0..4.

EXAMPLE

a(4)=11 because 11^4=14641 and for 1<i<11, i^4 is not a palindrome.

MATHEMATICA

a[n_]:=(For[m=2, !FromDigits[Reverse[IntegerDigits[m^n]]] ==m^n, m++ ]; m); Table[a[n], {n, 0, 4}]

CROSSREFS

Sequence in context: A217503 A165466 A175392 * A164918 A147822 A084961
