I probably don't have the time to prove my mtc2 works correctly. So I
simply ask if somebody can verify this or gets different results
(well, this is not the proper way to find a solution I know but ...):

For 10000000000000000, I get

$ time ruby19 q161b.rb 10000000000000000
Found 78 numbers

real    0m0.932s
user    0m0.781s
sys     0m0.090s

$ time ruby19 q161b.rb 1000000000000000000000000
Found 274 numbers

real    0m6.740s
user    0m6.319s
sys     0m0.110s

Did I miss a number?
