Also, palindromic numbers and strobogrammatic numbers sometimes attract attention of mathematician ambigrammists.
2 and 5 remain the same when viewed upside down, and turn into each other when reflected in a mirror. In the display of a calculator that can handle hexadecimal, 3 would become E upon either reflection or upside down arrangement, but E being an even digit, the three cannot be used as the first digit because the reflected number will be even ...
