List of Palindromic Squares
from length 32
rood Palindromic Squares rood Squares upto length 31
rood The Subsets rood Factorization rood comments



Legend

In the table below you'll find all the palindromic squares numbers I found so far.

 background color for the sporadic non palindromic basenumbers
 sidecells background color designate the sporadic palindromic squares with EVEN length
 sidecells background color designate the sporadic palindromic squares with ODD length
 sidecells background color designate the basenumbers with a CORE middle number in it
 background for the prime basenumbers


Also, numbers with a palindromic basenumber from length 32 onwards are no longer
listed exhaustively as they become too numerous. To keep the aesthetic look of the table
acceptable only the most interesting palindromic numbers are restrained i.e. those with
a non palindromic basenumber.
