minus-squareMarkus Redeker@mathstodon.xyztoMathematics@lemmy.ml•A curious math problem I came up with: given a target, what's the fewest digits an integer must have (in a given base) to contain all integers from 0 to the target, as substrings?linkfedilinkarrow-up4·edit-28 months ago@oblomov @mathematics @[email protected] @[email protected] No solution, but the problem is related to de Bruijn sequences (https://en.wikipedia.org/wiki/De_Bruijn_sequence), for which there exists a lot of literature. linkfedilink
