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 …

Almost "dense" subsets of primes (and may be not only primes)
Some criteria are not interesting if they involve digits base 10 - this is just a numerology (for example, delicate primes). …

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 …
