In combinatorial mathematics, a derangement is a permutation of the elements of a set, such that no element appears in its original position.
(source: Wikipedia. I have always struggled with mathematics, let combinational aside!)
@clearday thank you! @helenhall me too! Lol, this is what I call serendipity; I had taken these fiv poses and was googling “mathematical functions with five elements,” and I stumbled in that “derangement” expression and definition. And I found it so very fitting for myself I couldn’t resist! @kali66 oh thank you so much, Kali. The expression is a total puzzle for me, too. Only the definition I understand and... well, it’s me! @francoise hahaha, not me certainly! @wenbow thank you so much, Wendy! @mikegifford thank you, Mike!
