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?
There are SUM(FACT(5)/(FACT(k)*FACT(5-k)), for k = 1 to 5 combinations of Flaps, Fleps, Flips, Flops and Flups -- i.e., 31 combinations.
Excluding the combinations where Flaps, Fleps and Flips are not Flops, leaves 17 combinations. Further, excluding from the remaining combinations where Fleps are not both Flips or Flops leaves 13 combinations. And these are:
- Flap Flep Flip Flop Flup
- Flap Flep Flip Flop
- Flap Flip Flop Flup
- Flep Flip Flop Flup
- Flap Flip Flop
- Flap Flop Flup
- Flep Flip Flop
- Flip Flop Flup
- Flap Flop Flup
- Flip Flop Flup
- Flop Flup
- Flop
- Flup
Therefore,
a) No. There is only one possible combination (#13) in which exists a creature that is not a Flop. That creature could only be
a Flup.
b) Yes. There are only two possible combinations (#1 & #2) where a Flap is also a Flep. In both cases the creature is also a Flip.
c) Yes. Of the two possible combinations where a Flap is also a Flep, one of the combinations is where the creature is also a Flup (#1).
d) Yes. Only one combination (#1) exists where a Flup is both a Flap and a Flep. This combination also has the creature as a Flip and a Flop.
