MathWorld is, not surprisingly, not quite right. They mean to say consecutive primes, as "consecutive numbers" is obviously wrong.
The OEIS Wiki has a better page than Mathworld: https://oeis.org/wiki/Prime_constellations It separates the idea of a cluster from a constellation. Matt's page starts by talking about the standard triplets but then notes we can also find 3clusters. These are not consecutive primes. Code:
# replace ... by your list of a,b,... for p,p+a,p+b,... # perl Mntheory=:all E 'say for sieve_prime_cluster(<from>,<to>, ...); # e.g. one of Matt's clusters:' perl Mntheory=:all E 'say for sieve_prime_cluster(0,1000,102,246);' # or this random meaningless one: perl Mntheory=:all E 'say for sieve_prime_cluster(0,1e6, 102,246,384,512,770,896);'
