CREATE TABLE table_5742 ("Records" TEXT, "Pct." FLOAT, "MRC Championships" FLOAT, "Solo" FLOAT, "Co-Champions" FLOAT, "State Champions" FLOAT)

What is the highest value for co-champions when the PCT is less than 0.786 and MRC championships is 6 with records of 88-45-6?
SELECT MAX("Co-Champions") FROM table_5742 WHERE "Pct." < '0.786' AND "MRC Championships" = '6' AND "Records" = '88-45-6'
