[seqfan] Re: A033035: Change of parity

[Harry J. Smith]

This should be obvious, but

{7, 10} = {7, 11} base 9
{70, 91} = {77, 111} base 9
{637, 820} = {777, 1111} base 9
{5740, 7381} = {7777, 11111} base 9
{51667, 66430} = {77777, 111111} base 9
{465010, 597871} = {777777, 1111111} base 9
{4185097,5380840} = {7777777, 11111111} base 9
{37665880, 48427561} = {77777777, 111111111} base 9
{338992927, 435848050} = {77777777, 1111111111} base 9

So it is very easy to extend this.
