COMMENTS
| This sequence can also be produced by Sqrt[11111111111111111111111111111111111111111111] =11*Sqrt[91827364554637281910009182736455463728191], where Sqrt is the square root. In fact we found this from the square root and later looked for the same sequence in the expansion.
Comment from Eric Desbiaux (moongerms(AT)wanadoo.fr), Apr 08 2008: Also, of course, decimal expansion of 9/9801. Note that
99/9801 = 0.0101010101010101010101...,
9999/9801 = 1.02020202020202020202020...,
999999/9801 = 102.0303030303030303030303...,
99999999/9801 = 10203.040404040404040404040404..., etc.
