In particular, instead of solving F2L completely, one can solve F2L minus one pair and then fix the parity before solving the last 5 edges and then the last 5 corners as described in the linked post. Although you can solve the Pyraminx by starting with any color, yellow is highly recommended as it is similar to the white face of the Rubiks cube. If you want to further understand the cube and not rely on any memorized algorithms at all, you should take a look at this post on solving general permutation puzzles, which includes a section on the 3×3×3 cube. As a beginner, choosing to begin with the yellow-colored face is most common and highly recommended. Solve the last corner-edge pair in any way you want.You see, you can rotate the bottom layer to align that unsolved corner with any middle layer edge position and then easily chuck the edge piece in (because you do not care about messing up the unsolved corner). Use the unsolved bottom corner to facilitate solving 3 of the middle layer edges.Solve only 3 corners on the bottom layer.Since it seems that you are not looking for just memory work (otherwise you should just memorize all the F2L pair algorithms), I recommend you instead solve F2L as follows: However, it is clearly troublesome otherwise. As someone commented, F2 U2 F2 U2 F2 works if the edges in question are oriented suitably. The standard F2L pair algorithms cover all cases, but if you want intuitive rather than fast solution then actually you should not solve layer by layer.
