Numerology with Ramanujan's pi formula

Given Ramanujan's famous $\frac1{\pi}$ formula $$\frac 1\pi=\frac {2\sqrt2}{99^2}\sum_{k=0}^\infty\frac {(4k)!}{k!^4}\frac {26390k+1103}{396^{4k}}$$ which is a level 2 Ramanujan-Sato series. It can …

Intersection of $\mathrm{PGL}_2(q_0)$'s in $\mathrm{PGL}_2(q_0^3)$

$\DeclareMathOperator\PGL{PGL}\DeclareMathOperator\GL{GL}$I would like an explanation for some strange numerology which I encountered when studying intersections of subfield subgroups in $\PGL_2(q)$. … Under this assumption we have the following remarkable numerology: If $L\cong C_{q_0-1}$, then $|x(L)|=q_0^2+q_0 = |H: L|$. If $L\cong C_{q_0+1}$, then $|x(L)|=q_0^2-q_0 = |H:L|$. …

Another Goldbach variation for odd numbers?

Dabbling in the dark art of numerology, one observes that every odd integer $2n+1\geq 5$ up to $10^7$ (where my computer got somewhat tired) can be written as $$2n+1=p+2^kq$$ with $p$ a prime, $k$ an integer …
