A Meertens number in base n is a fixed point of the base n Godel encoding
The base n Godel encoding of x is 2^d(1) * 3^d(2) * ... * prime(k)^d(k), where d(1)d(2)...d(k) is the base n representation of x.

In a computer search that included all numbers < 10^29 and bases <= 16, the only additional Meertens numbers found were 6 (base 2), 10 (base 2), 49000 (base 5), and 181400 (base 5).
There is no base 11 Meertens number < 11^44 ~= 6.6*10^45.
There is no base 12 Meertens number < 12^40 ~= 1.4*10^43.
There is no base 13 Meertens number < 13^39 ~= 2.7*10^43.
There is no base 15 Meertens number < 15^37 ~= 3.2*10^43.
Other terms: a(17) = 36, a(19) = 96, a(32) = 256, a(51) = 54.  Chai Wah Wu, Aug 28 2014
