Thread: Hasse diagram (tough one)

Hi there I wanna check these answers for the attached hasse diagram:

a)upper bound of {a,b,c} - my answer -> l only
b)least upper bound of {a,b,c} my answer -> l
c)lower bounds of {f,g,h} my answer -> none
d)greatest lower bound of {f,g,h} -> none


This diagram is really weird!

Nope. See there is a path from a, b and c to k, l and m

b)least upper bound of {a,b,c} my answer -> l

have a look at k.

c)lower bounds of {f,g,h} my answer -> none
d)greatest lower bound of {f,g,h} -> none

I'd say, yes ^^

This diagram is really weird!

There are worse
