A BAB for the number 155 was created because 155 wsa the smallest number that didn't have a nBAB. Creating a nBAB for the number 155 resulted in the number

156becoming the next smallest number without a nBAB.In addition, the number

156was used for example purposes in About Number BABs (nBABs) that was created on 18 December 2013.Note: This nBAB was created when MathBabbler was a century away from turning
