a(2) = 20 because there are 20 cyclotomic cosets of 9 mod 100:
{1, 9, 81, 29, 61, 49, 41, 69, 21, 89}
{3, 27, 43, 87, 83, 47, 23, 7, 63, 67}
{11, 99, 91, 19, 71, 39, 51, 59, 31, 79}
{13, 17, 53, 77, 93, 37, 33, 97, 73, 57}
{2, 18, 62, 58, 22, 98, 82, 38, 42, 78}
{4, 36, 24, 16, 44, 96, 64, 76, 84, 56}
{6, 54, 86, 74, 66, 94, 46, 14, 26, 34}
{8, 72, 48, 32, 88, 92, 28, 52, 68, 12}
{10, 90}
{30, 70}
{20, 80}
{40, 60}
{50}
{5, 45}
{15, 35}
{55, 95}
{65, 85}
{25}
{75}
{0}
