I transposed two digits in posting above. 

P:\test>type junk.pl
sub is_rotatable{

}

printf "%s %s rotatable\n", $_, is_rotatable( $_ ) ? 'is' : 'not'
        for 33, 131, 141, 171,
        25696925, 101, 88;


P:\test>junk
33 not rotatable
131 not rotatable
141 not rotatable
171 not rotatable
25696925 is rotatable
101 is rotatable
