The problem lies in p+1, the necessarily composite p+1 can comply with condition for exiting while

comment Finding primes that have certain property
your code does not produce only primes: note-19980,28980,29790,29880, etc

@Mr.Wizard it never ceases to amaze me how much I learn from your code and how I over complicate measures...:)

comment Next highly composite number?
@Sasha FYI nextn(1230233,factors=c(2,3,5,7,11)) in R also yields...1232000 but I assume you already know that

comment Next highly composite number?
@Sasha thank you for the instructive advice...my time limited aim was to reproduce the R implementation and agree entirely subset for large list of primes would be unwieldy but for specified purpose, most of time 3 primes, not too expensive...but accept entirely your more efficient code.
