More a logic than a programming question

hello,

I'm a littlebit lost...

i have a table of single names and combination of two names and i want a table of ALL single names with ALL combinations (also the indirect ones).

- - - in reality the names are longer, not only a,b,.. and the table is tab-delimited, and the result table should also be tab-delimited - - -

input (is NOT sorted, only here for demonstration)

Code:

a
b
b c
c
c d
d
d c
e
f
f e
g
g c
h

output

Code:

 
a a
b b,c,d,g
c b,c,d,g
d b,c,d,g
e e,f
f e,f
g b,c,d,g
h h

Result: remove all redundancies, show all connections and sorted second column.

probably someone can give me some hints and code snippets (i know awk a little bit and can finish the program...)

thanks a lot,

dietmar
