\$\begingroup\$ Out of curiosity, why does Jelly even have the builtin ṃ "Base decompression; convert x to base length(y) then index into y."? Is it for the very exceptional cases where the base you ant to convert to and length of a string/integer/list are equal? When I search for it, I can only find three answers using it: 1; 2; 3. Kinda a weird builtin in every day code-golf challenges imo. :S \$\endgroup\$

\$\begingroup\$ @KevinCruijssen it's very useful when you want, for example, to convert N to hexadecimal using hex letters instead of a list of numbers. \$\endgroup\$

\$\begingroup\$ @KevinCruijssen It's a compression method for strings. In the first example the string desired is “sspspdspdspfdspfdsp”, but with “çƥ÷£ḟ’ṃ“spdf”¤ you save six bytes. It's especially useful with Jelly's base 250 numbers \$\endgroup\$
