       this is my current keycap set for my desktopall the function key symbols relate in some way to the corresponding number, i’ll elaborate in replies

       F1: S0 = 1, the successor of 0, as in Peano arithmeticF2: ℂ, the complex numbers, a two-dimensional spaceF3: F₄, the fourth Fibonacci number, which is 3F4: ℍ, the quaternions, a four-dimensional spaceF5: ∄, 'there does not exist': a reference to the Abel-Ruffini theorem proving that there does not exist a formula giving the roots of degree-5 polynomials in terms of the coefficients and the standard arithmetic operationsF6: 3! = 6

       F7: ×, the cross product, can be defined only in 1, 3, and 7 dimensions.F8: 𝕆, the octonions, are an 8-dimensional spaceF9: √-d is a reference to the nine Heegner numbers; d is Heegner if the field you get by extending the rationals with √-d has unique factorization.F10: K₅, the complete graph on 4 vertices, has 10 edges.F11: 11 is prime, and π is the prime-counting function. (Look, they can't all be clever.)

       F12: 6 is the first perfect number, and the sum (Σ) of its divisors (σ) is 12.ℵ₀, ω, and 𝖮𝗇 are different kinds of infinity. (𝖮𝗇 shows up in combinatorial game theory, represented by the class of all games.)The λ is the 'fn' key because lambda calculus.
