Trillions if not more of Semi-primes composites created within a large triangle number index. 

Hi all seqfans, 

RSA2048 falls on that very same triangle number index. 
This uses rsa2048 which has 617 digits and the 
two prime divisors forming the semi-prime have 309 digits 
for each prime. 
These primes are almost divisors of RSA-2048 and the two assending 

list are sequences.
