Table schema:
CREATE TABLE table_name_63 (assists INTEGER, total_attempts VARCHAR, percentage VARCHAR, solo_blocks VARCHAR)

Question: When the percentage is 0.34900000000000003 with more than 13 solo blocks and less than 4713 total attempts, what is the greatest assists?
SQL: SELECT MAX(assists) FROM table_name_63 WHERE percentage < 0.34900000000000003 AND solo_blocks > 13 AND total_attempts < 4713
