x1=j2=p3 (ka; jo'u/fa'u term) is the minor difference in/between x2=p2 and x3=p1 that is to be ignored, their similarity being by standard/in geometry x4; x2 is the same as/similar to/parallels x3 in standard/geometry x4 up to/modulo/except for/ignoring unimportant difference x1;

x1 is not the focus of the main consideration concerning the similarity between x2 and x3; x2 belongs to/is an element of the same equivalence class as x3, which depends on x4 in some way and which ignores the property x1. For example, tetrominoes "L" and "7" are similar up to the unimportant property of 90-degree rotation; thus: loka carna keiku ly terpanryziltolju'i zebu loka mapti. x2 and x3 are symmetric; while with panra, x1 (which is x3 in terpanryziltolju'i) is possibly of importance/focus/attention, for terpanryziltolju'i, x2 is. Additionally, lo panra and lo se panra are identical, therefore conversion under te does not affect the x2 and x3 positions of panra, so the overall structure does not need to have undergone an additional conversion.
