I don’t know why you’d want to remember the number, but this one seems easy if you know some memory techniques.

> Remember that vuln 111-497 (as two chunks)

Good first step. Remember it’s two sets of three numbers. The first set is all ones, meaning the first three numbers are 1, then the fourth number is 4, then you add five for the next one (9), then you have to remember to subtract two (7)¹.

May sound silly, but I bet some of you have already memorised it from that alone. Being a slightly convoluted by still logical set-by-step helps with recollection.

¹ Lot of different ways to go about that, like remembering that the first set was three of one so “two was left out”.
