How can i generate a same series of random number until press a button? I can't set the seeds to perform this action.

for example:
when press named "A" button to generate a series of number(1,2,3,4,7...), and press it again, the series of number is still 1,2,3,4,5... until press anothe button

one more question, it is possible to generate number in ascending or descending
order?
