Miner's Second Number (MISEN for short) is the second number[1] created by Miners.
Formula:
K 1 ( 0 ) = ℵ 0 {\displaystyle K_1(0)=\aleph_0}
K 2 ( 0 ) = ℵ ℵ 0 {\displaystyle K_2(0)=\aleph_{\aleph_0}}
K 3 ( 0 ) = ℵ ℵ ℵ 0 {\displaystyle K_3(0)=\aleph_{\aleph_{\aleph_0}}}
...
K 119 ( 0 ) = ℵ ℵ ℵ . . . 0 {\displaystyle K_{119}(0)=\aleph_{\aleph_{\aleph_{..._0}}}}
K 120 ( 0 ) = ℵ ℵ ℵ . . . 0 {\displaystyle K_{120}(0)=\aleph_{\aleph_{\aleph_{..._0}}}}
K n ( d ) = ℵ n t i m e s d {\displaystyle K_{n}(d)=\aleph_{n times_d}}
Conclusion: Miner's Second Number= K 120 ( 0 ) {\displaystyle K_{120}(0)} = K 120 ( 0 ) = ℵ ℵ ℵ . . . 0 {\displaystyle K_{120}(0)=\aleph_{\aleph_{\aleph_{..._0}}}} .
