I think our key could be a certain number. I remember reading something along the lines of "the key is 5 and 5 your hands are a reminder". Now 55 is in a lot of stuff.

Triangular Numbers

0, 1, 3, 6, 10, 15, 21, 28, 36, 45, [55], 66, 78, 91, 105, 120, 136, 153, 171, 190, 210, 231, 253, 276, 300, …

Square Pyramidal

1, 5, 14, 30, [55], 91, 140, 204, 285, 385, 506, 650,…

Fibonacci

1,1,2,3,5,8,13,21,34,[55],89,144, …

Heptagonal Numbers [(5n^2-3n)/2]

1, 7, 18, 34, [55], 81, 112, 148, 189, …

Trianglar numbers are cool. The sum of any 2 consecutive ones is a square. Square pyramidals are also cool. The sum of squares up to n is a square pyramidal. Then fibonacci is the sum of previous terms. Heptagonal can be broken into the three thing in pic related. Also heptagonal numbers have to do with 7 sides, which is a holy number.

Another thing I recently learned is that if you take any 2 numbers, a and b, and do the fibonacci sequence with them, the sum of the first 10 numbers will be equal to the 7th number times 11.

term sum

1: a a

2: b a+b

3: a+b 2a+2b

4: a+2b 3a+4b

5: 2a+3b 5a+7b

6: 3a+5b 8a+12b

7: 5a+8b 13a+20b

8: 8a+13b 21a+33b

9: 13a+21b 34a+54b

10: 21a+34b 55a+88b

And it is obvious that (5a+8b)*11 = 55a+88b.

Maybe we can use this stuff to help us find de wey
