CREATE TABLE table_42761 ("Element" CLOB, "Nuclide" CLOB, "Z  (  p  ) " FLOAT, "N  (  n  ) " FLOAT, "isotopic mass  (  u  ) " CLOB)

What is the highest Z (p) when arsenic is the element, and the N (n) is more than 42
SELECT MAX("Z ( p )") FROM table_42761 WHERE "Element" = 'arsenic' AND "N ( n )" > '42'
SELECT MAX("Z ( p )") FROM "table_42761" WHERE "Element" = 'arsenic' AND "N ( n )" > '42'
