Operations with consecutive integers

Find consecutive integers that when multiplied together creates a palindrome.

The number 77 steals the show :
77 * 78 = 6006
77 * 78 * 79 = 474474

Note also that 77 is expressable as the sum of three squares
4 2 + 5 2 + 6 2

Readers are invited to send me more of these. The larger the better !

474474 is also a palindromic area of a primitive Pythagorean triangle
with sides 1562 + 60832 = 60852
