A bit more than that....
111
111=37X3
Elevenses and Eleventy-One, as with most palindromic numbers, are very "Hobbit forming".
111²=12321
111³=1367631
1111²=1234321
11111²=123454321
111111²=12345654321
1111111²=1234567654321
11111111²=123456787654321
111111111²=12345678987654321
Here's a way to waste an afternoon:
Take a three digit number, reverse the digits and add them,
take the sum, reverse the digits and add, repeat this process
until you get a Palindromic Number, Examples:
195+591=786
786+687=1473
1473+3741=5214
5214+4125=9339
9339 is palindromic.
Let's try this with 197:
197+791=988
988+889=1877
1877+7781=9658
9658+8569=18227
18227+72281=90508
90508+80509=171017
171017+710171=881188
881188 is palindromic
Try this process for 196 and you will waste more than an afternoon,
196 does not form any palindromes at all.
There are many of these Lychrel Numbers that have vexed many of us number buffs. Enjoy!!
Number 89 has some interesting properties. For further reading check out:

112
112 has a few other properties
