Yes, Michel, you are right.  I am sorry for the mistake.
The intention was just to exclude [-oo, -oo] and [+oo, +oo] ...

Don't be sorry -- you are right too!  John's specification was in fact
incomplete:


   That is, the nonempty members of T comprise all
   intervals xx=[xlo,xhi], where xlo and xhi are F-numbers.

What's missing is: ... and xlo is not +oo, and xhi is not -oo

Very tricky, Michel, but excellent. Congratulations.
Ulrich

Kaucher enthusiasts may scream if we add:  and xlo<= xhi

Michel.
