If the 0 before the decimal point is not counted, then a(1) = 5, a(10) = 6, and a(18) = 4.

Examples

			a(3) = 5 because 5 is the first digit to appear 3 times in the decimal expansion of gamma = 0.(5)7721(5)664901(5)...

Maximal information-based nonparametric exploration statistical analysis program (MINE), which I applied "pairwise" to the first 62 terms, shows high values (up to 1) of the maximal information coefficient (MIC), which is a measure of two-variable dependence designed specifically for rapid exploration of many-dimensional data sets - see supplied links. - Alexander R. Povolotsky, Sep 07 2012
Computationally intractable question: what is the last term to appear, assuming all 9*9! terms eventually show up? - Charles R Greathouse IV, Sep 07 2012
