### How it works

 ;.{tfk+}ᵃ⁽{k≠&t}ℕ implicit input n
 ;. [n, output]
 { }ᵃ⁽ starting with [output], generate a list
 by applying {…} n times:
 t the last element's
 f factors
 k without itself
 + summed
 -> [220, 284, 220]
 {k≠&t} the generated list must fulfill:
 k≠ without the last element, all elements are different
 &t and the tail
 is the implicit output
