. There are 6 cases of three digit palindromes: abcba, abccba, ababa, aaaaa, aaaaaa, bbbaaa
    . where a,b,c are digits and 9 > a,b,c > 0
    . Expanding this to polyatomic forms, we have:
    1) x = abcba = 10001a + 1010b + 100c
    2) x = abccba = 100001a + 10010b + 1100c
    3) x = bbbaaa = 111000b + 111a
    4) x = ababa = 10101a + 1010b
    5) x = aaaaa = 11111a
    6) x = aaaaaa 111111a
