Theorem indistpsx 22989
Description: The indiscrete topology on a set 𝐴 expressed as a topological space, using explicit structure component references. Compare with indistps 22990 and indistps2 22991. The advantage of this version is that the actual function for the structure is evident, and df-ndx 17159 is not needed, nor any other special definition outside of basic set theory. The disadvantage is that if the indices of the component definitions df-base 17175 and df-tset 17234 are changed in the future, this theorem will also have to be changed. Note: This theorem has hard-coded structure indices for demonstration purposes. It is not intended for general use; use indistps 22990 instead. (New usage is discouraged.)
