Dual space of $\ell^\infty$
I have added clarification of the question. (Since it already has been bumped by Asaf's edit.)

Approximating integers with prime quotients
Some posts on Math.SE:
Rationals of the form $\frac{p}{q}$ where $p,q$ are primes in $[a,b]$.
,
The set of rational numbers of the form p/p', where p and p' are prime, is dense in $[0, \infty)$
and
Are fractions with prime numerator and denominator dense?
. Related MO post:

Is an inclusion of finite groups with boolean lattice, linearly primitive?
Sorry, now I noticed that your question is about
finite
groups. But I will keep comment, just in case it is useful for other users reading this question.

Is perhaps this result of Tůma useful for answering this question?
Every algebraic lattice is isomorphic to an interval in the subgroup lattice of some group.

Antichain on $\mathcal{P}(\omega)/fin$ of cardinality $2^{\aleph_0}$?
BTW proof in Asaf's post can be considered as a typical example of
"transfer via bijection"
