Hi, all,

            Happy New Year 2024 to all of you

but before 2023 truly elapses, this fateful year which brought us the awesome HP-15C CE, let's amazing-grace it with a final teaser for those of you who would accept it. Very succinctly, concisely and even tersely:

You all know the matrix Determinant, aka det. Now, the matrix Permanent, aka per, is defined likewise but with all signs positive, no negative terms, i.e. like this:



and the teaser is that you use the new Christmas toy calc you got last Dec, 25th (or any other, for that matter) to obtain the permanent of this nice little matrix I just lovingly concocted specially for you. The result is sure to surprise you !

Admittedly this teaser is only for power calc users so don't feel too bad if you're not up to the task (I only needed 3 lines of code for my 4-decades old toy.)

Best regards and, again, Happy New Year 2024 !
