I have an 4 x 23 array of random numbers currently made using randbetween. However, I want to be able to regenerate the exact same combination of numbers as needed.

Context: I teach high-school maths and use spreadsheets for generating random numbers or random questions. I have set up question for revision, where each student gets four random questions from a large set. I have the answers already created and so I would like to be able to access the answers for each student again based on the seed used to generate the random questions.
