CREATE TABLE table_68994 ("Material" TEXT, "Resistivity  ( 10 \\u22126 ohm-inches ) " FLOAT, "Relative permeability" FLOAT, "Skin depth ,  inches" FLOAT, "Surface resistance ,  Relative to copper" FLOAT)

What is the sum of skin depth with a resistivity of 1.12 and a relative permeability larger than 1?
SELECT SUM("Skin depth, inches") FROM table_68994 WHERE "Resistivity (10 \u22126 ohm-inches)" = '1.12' AND "Relative permeability" > '1'
SELECT SUM("Skin depth, inches") FROM "table_68994" WHERE "Relative permeability" > '1' AND "Resistivity (10 \u22126 ohm-inches)" = '1.12'
