%N A101754 Numbers n such that the sum of the first n decimal places of Catalan's 
               constant is prime.
%e A101754 The sums of the first n decimal places of Catalan's constant are listed 
               in A099616: 9, 10, 15, 24, 30, 35, 40, 49, 53, 54, 61, ... Of these, 
               the first one that is prime is 53 which is the 9th term. The first 
               term in our sequence is therefore 9. The partial sum 61 is also prime 
               and this appears in the 11th place, so the second term of our sequence 
               is 11.
