Smallest 18 Primes in Arithmetic Sequence/Historical Note

Historical Note on Smallest 17 Primes in Arithmetic Progression
, in his of $1986$ reported that this was the longest known arithmetic progression of prime numbers.

As put it:
 * breaking the previous record of $17$ due to Weintraub.

The Weintraub in question was, who had discovered the previous record of $17$ such primes in $1977$.
