Miner's Super Arrow Number

This is a bigger Miner's Arrow Number, and this number is Graham's number times zero percent of the size of the Omniverse in Multiversal diameters.

Sadly, it doesn't end with 121 steps.

Formula:

$$MSa_0 = Ma_{Ma_{0}}$$, or simply $$MSa_0 = Ma_2$$.

$$MSa_1 = Ma_{Ma_{Ma_{Ma_{1}}}}$$

$$MSa_2 = \overbrace{Ma_{Ma_{..._{Ma_2}}}}^{Ma_2\text{ Ma's}}$$

$$MSa_3 = \overbrace{Ma_{Ma_{..._{Ma_3}}}}^{Ma_3\text{ Ma's}}$$

$$\cdots$$

$$MSa_{119} = \overbrace{Ma_{Ma_{..._{Ma_{119}}}}}^{Ma_{119}\text{ Ma's}}$$

$$MSa_{120} = \overbrace{Ma_{Ma_{..._{Ma_{120}}}}}^{Ma_{120}\text{ Ma's}}$$

$$MSa_{121} = \overbrace{Ma_{Ma_{..._{Ma_{121}}}}}^{Ma_{121}\text{ Ma's}}$$

$$MSa_{122} = \overbrace{Ma_{Ma_{..._{Ma_{122}}}}}^{Ma_{122}\text{ Ma's}}$$

$$MSa_{n} = \overbrace{Ma_{Ma_{..._{Ma_{n}}}}}^{Ma_{n}\text{ Ma's}}$$

Conclusion: This number is really big, maybe even bigger than the salad-number ending "OH NO" number. Maybe it's even bigger than TREE(3) or TREE(4)? We will never know. And it is MSa122.
