CREATE TABLE table_68992 ("Material" CLOB, "Resistivity  ( 10 \\u22126 ohm-inches ) " FLOAT, "Relative permeability" FLOAT, "Skin depth ,  inches" FLOAT, "Surface resistance ,  Relative to copper" FLOAT)

What is the lowest relative permeability with a skin depth larger than 0.112 inches?
SELECT MIN("Relative permeability") FROM table_68992 WHERE "Skin depth, inches" > '0.112'
