 A178161 Number of n-digit Type-2 Trott-like Constants (see A178160 for definition). 1
 9, 63, 296, 693, 4117, 14071, 79586, 232069, 1356627, 4222935, 24394044, 73910079, 429075206, 1314629842 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS The values given as a(4), a(8), and a(11) each include exactly one type-2 Trott-like 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. LINKS EXAMPLE There are 63 type-2 Trott-like 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.
