Flaps, Fleps, Flips, Flops, and Flups (Posted on 2008-11-16) Difficulty: 2 of 5
All instructed people know that Flaps, Fleps and Flips are simply forms of Flops.

It is proved moreover that all Fleps are both Flips and Flops.

However there is a complication: Recently one found out that there are some Flips which are neither Flaps nor Fleps nor Flups, and in addition one found out that there are some Fleps which are neither Flaps nor Flups.

Admittedly, some Flaps and some Fleps and some Flups are Flips.

And now we know more about Flups: Some are Fleps, some are Flips, and some are both Flaps and Fleps.

In this common universe:

a) Are there Flips which are Flups, which are not Flops?

b) If a Flap is a Flep, then is it always a Flip?

c) If a Flap is a Flep, some of them could it be a Flup?

d) There is a creature that is both a Flap and a Flep and a Flip and a Flop and a Flup?

"some Flaps and some Fleps and some Flups are Flips" attests to the existence of all four categories mentioned, and since three of those are also Flops, the existence of that fifth category is also assured. So no existential assumption is needed other than what's given.
