Some signs, with shapes below them.
Reals ℝ, complex ℂ: a single circle
Rationals ℚ: a figure-8
p-adic ℚ2, ℚ3, ℚ5, ℚ7: a figure-8 and a line
Integers mod 181 ℤ/181ℤ, Rationals adjoin √46 ℚ[√46]: a figure-8, two circles, and three lines
Caption: No one ever wants to use the topology department's fields.
