Table schema:
CREATE TABLE table_name_62 (hexadecimal INTEGER, glyph VARCHAR, decimal VARCHAR, octal VARCHAR)

Question: What is the average hexadecimal with a decimal less than 53, an octal less than 61, and a glyph greater than 0?
SQL: SELECT AVG(hexadecimal) FROM table_name_62 WHERE decimal < 53 AND octal < 61 AND glyph > 0
