splitting rows sql

can someone greatfully let me know opposite segments 3 rows intersecting opposite ways controlling sql? 3 rows #t2 paint sets a,b, c - i am looking i b, i c, b i c, i b i c, a' , b', c' etc., (7 illusory segments 3 rows venn diagram) where i intersection.

i am looking general fortitude hoop n array rows #t2.

-- sql formula begin
create list #t1 (key1 int, key2 int) -- any key1 there 1 some-more key2
go
create list #t2 (row_id int identity(101, 1), key1 int) --row_id primary key
go 

insert #t1
select 1, 11 kinship name 1, 12 kinship name 1, 13 kinship name 1, 14 kinship 
select 2, 13 kinship name 2, 15 kinship name 2, 16 kinship name 2, 17 kinship 
select 3, 13 kinship name 3, 12 kinship name 3, 16 kinship name 3, 17

-- 1 --> 11, 12, 13, 14
-- 2 --> 13, 15, 16, 17
-- 3 --> 13, 12, 16, 17

insert #t2 (key1)
select 1 kinship name 2 kinship name 3

-- sql formula end

the cost i am looking is,

1001  11 (a')
1001  14 (a')
1002  12 (a i c - i b i c)
1003  13 (a i b i c)
1004  15 (b')
1005  16 (b i c - i b i c)
1005  17 (b i c - i b i c)

the cost 5 segments, instead illusory 7 twin null.
