Pandigital 1253098674 lies at the base of a palindromic curiosum
Patrick De Geest

But transform this square into its “ base 5 ” representation
and you suddenly get the following palindrome

101133013113000311310331101

of length 27 digits. Note the absence of the digit 4.

Exist there also a ninedigital equivalent ?
And what about the variant using cubes and higher powers ?
