COMMENTS

The values given as a(4), a(8), and a(11) each include exactly one type2 Trottlike constant that cannot be extended to additional digits (see A178164). All the rest, including every constant counted in each of the other terms, can be extended by an arbitrary number of additional digits.

EXAMPLE

There are 63 type2 Trottlike constants that have exactly 2 digits after the decimal point (0.11 ... 0.16, 0.21 ... 0.27, 0.31 ... 0.37, 0.42 ... 0.48, 0.52 ... 0.58, 0.62 ... 0.68, 0.72 ... 0.78, 0.82 ... 0.88, and 0.92 ... 0.99), so a(2) = 63.
