Here we had kind of the same issue but it was more or less clear what we were searching. So our magician swang his wand and we have this time R code:```rmyfunction <- function(n) {  out <- NULL  for(a in 1:floor(sqrt(n))) {    b <- floor(sqrt(n - a^2))    if(a^2 + b^2 == n) {      out <- rbind(out, c(a, b))    }  }  return(out)}```So the flag was *KCTF{90,130}*
