Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_68992 ( "Material" text, "Resistivity (10 \u22126 ohm-inches)" real, "Relative permeability" real, "Skin depth, inches" real, "Surface resistance, Relative to copper" real )

### Question ###
What is the lowest relative permeability with a skin depth larger than 0.112 inches?

### Accurate SQL ###

SELECT MIN("Relative permeability") FROM table_68992 WHERE "Skin depth, inches" > '0.112'
