# Set N(210)

**If:**

**N _{210} = {2^{Nᴜ{0}}} x {3^{Nᴜ{0}}} x {5^{Nᴜ{0}}} x {7^{Nᴜ{0}}}**

**Pu = (P ∪ {1})\ _{{2,3,5,7}}**

**Q= [Pu x Pu] ^{N}**

**Then: **

**N = N _{210} ᴜ {(6N + 5N_{210})} ᴜ {(6N + 7N_{210})}**

**N = N _{210} x ({1} ᴜ (6(Pu ᴜ Q) + {5})) ᴜ (6(Pu ᴜ Q) + {7})))**

**N = N _{210} x ({1} ᴜ (6Pu + {5,7}) ᴜ (6Q + {5,7}))**

**N2 = N _{210} x ({2} ᴜ 6(Pu ± {1}) ᴜ 6(Q ± {1}))**

**N2 = {2} x N _{210} x ({1} ᴜ 3(Pu ± {1}) ᴜ 3(Q ± {1}))**
