Jul 10 at 21:05 comment added Hans @alanf: I have answered my own question. Feel free to inspect it. As for the statement of the product of $\pm1$, there are of course $4$ cases. I alluded to this in the last two sentences of my question. The question is how this combinatorics is specifically applied, since there are many interpretations and applications of this combinatorics. Option 1 and 2.1 in my answer demonstrate two distinct applications.

Jun 23 at 19:03 comment added Hans @alanf: I have added the page number and edition year. I have said it was from F-3-b with the equation number. The very first phrase of F-3-b.$\alpha$ is "Relation (B-10)..." which is in Section B not in Section F contrary to what you say. $\hat A, \hat B$ -- not $A, B$ --are used for the first time in Equation (F-7) in Chapter XXI Section F but not explicitly defined. If you refer to the sentence in the parenthesis, it only says they are operators not numbers. I do not understand your hint for the sign. Could you please write an answer?

Needs details or clarity
Jun 23 at 9:06 comment added alanf Page references as well as what edition you're using would be helpful. If you're asking about F-3-a and F-3-b, the relevant content is from those sections, not from elsewhere in the book. The authors define the operators in the equation you quote in the sentence immediately preceding the equation you quoted and the paragraph before the paragraph giving (F-1) and (F-2) is also relevant. As a hint for where the signs come from: what are the various products of $\pm 1$?
