The explicitly typed relation R⊆Fin(2)×Fin(2) has ordered pairs=[[0, 0], [1, 1], [0, 0]]. Normalize repeated pairs as a set, in lexicographic order. A relation need not be single-valued or total; its converse need not be an inverse function. Give ([n,m], normalized pairs, each source fiber size, at-most-one value per source?, exactly-one value per source?, total image table or not-a-total-function).
G001 — The explicitly typed relation R⊆Fin(2)×Fin(2) has ordered pairs=[[0, 0], [1, 1], [0, 0]]. Normalize repeated pairs as a set, in lexicographic order. A relation need not be single-valued or total; its converse need not be an inverse function. Give ([n,m], normalized pairs, each source fiber size, at-most-one value per source?, exactly-one value per source?, total image table or not-a-total-function).Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
Before
types=(2,2);raw ordered pairs=[[0, 0], [1, 1], [0, 0]]
After
normalized relation=[[0, 0], [1, 1]]
Conditions: none
Validate both types of every ordered pair,then deduplicate identical pairs.Swapping coordinates forms the converse,not a sorting of one pair.A relation may be multivalued or partial.
Rule: typed_relation_set_normalization · Uses: G001
Before
source=0;pairs=[[0, 0], [1, 1]]
After
outgoing values=[0];count=1
Conditions: none
Collect all distinct outgoing targets of every declared source;an absent source has an empty fiber.
Rule: relation_each_source_value_fiber · Uses: G001, S001
Before
source=1;pairs=[[0, 0], [1, 1]]
After
outgoing values=[1];count=1
Conditions: none
Collect all distinct outgoing targets of every declared source;an absent source has an empty fiber.
Rule: relation_each_source_value_fiber · Uses: G001, S002
Before
source fiber sizes=[1, 1]
After
single-valued=Yes;exactly-one total=Yes;table/status=[0, 1]
Conditions: none
At most one value permits missing sources;exactly one makes a total function.On an empty source both universal conditions are true and the table is empty.Repeating a pair does not increase a fiber size.
Rule: partial_single_valued_not_total · Uses: G001, S003

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
