Re:Numbers and their reversals

the reason of my previous question to mathgroup was that someone said that he has three weird numbers : 23 , 114 , 6236
he said that when we arrange these numbers in pairs side by side with the smaller number first , and after that we reverse the pair we will get:
23114=7*13*254
41132=7*13*452
236236=7*13*2596
632632=7*13*6952
1146236=7*13*12596
6326411=7*13*69521
he said that there are no other three numbers like these in all the world.
it happened that pairings of these numbers are a subgroup from many numbers such as: 22, 113, 7227
Thanks DrBob and Bob Hanlon and all for the in depth analysis and investigations
