[交流] how many words can u spell like this?

pat--tap
like the pair above, change the sequence of letter, and it is still a word

well, this is what i asked in an exam, in which people should write at least 10 pairs of that kind of words. unfortunately, i just write 5 pairs to answer the question. how many words can u spell in the way like that?

please write the answer without refer to baidu or dictionary. just think as in an exam for u, but without time limit

Let me try. A 3 or 4 digits composed word usually can be a good candidate to solve this question. PS: if the reversed word is not necessay to be another word, then it becomes easier.

dim-mid
pop-pop
bob-bob
peep-peep
poop-poop
no-on
eye-eye
knit-tink
dam-mad
rat-tar
dad-dad
mom-mom
eve-eve
but-tub
bat-tab
bud-dub
bad-dab
dew-wed
pal-lap
bus-sub
are-era
laid-dial
drib-bird
dib-bid
deed-deed
doom-mood
gum-mug
level-level
lag-gal
nap-pan
raw-war

Roughly after first 15 random trials, I started to do it alphabetically and found words began with "b" and "d" were easier to deal with. I suppose that using "b" and "d" leaded words could help to locate 10 matches in a shortest time.
