About the Number 437 (four hundred thirty-seven)

MathBabbler did an audit of the nBAB collection and the findings of that audit resulted in a change to the newnbab command and the creation of a postnbab command. There were 435 nBABs at the time of this audit and a nBAB for the number 436 already existed; therefore, the nBAB programs were tested using the number 437.
