September 2022 Ponder This
 
Looking at

LLLRH H
LRR HHH
LRRRH H,

I don’t see the symmetry. The second and the third L in the first line differ from the third line.
Is anyone able to explain, in what way that is symmetric?

Is there a difference between = and == ?
And what will say: “all the grid points in the letters are essentially generic points” ?

[QUOTE=Dieter;612963]<snip>

<snip>[/QUOTE]In Pari-GP scripts, = is an assignment operator. Thus "a = 1" assigns the value 1 to the variable "a".

But "==" is a comparison, result either TRUE (1) or FALSE (0). For example, the comparison

1 == 0

would give a result of 0 (FALSE).

Change every letter to *, then maybe you'll see it:

[CODE]***** *
*** ***
***** *
[/CODE]

It is already next month, we don't have the new question, heck we don't even have any updates or feedback on the solvers. This sucks!
