Single Curio View: (Seek other curios for this number) The sum of the squares of the first 41 semiprimes is itself a 4brilliant number (this being the first such solution). Note that 41 is the prime reversal of the semiprime 14, that 4brilliant means the product of 4*1 primes of the same number of digits, and that 41 is one of those primes. [Post]
