Over Partition Sql in LINQ

Hi, i'm here and i want to learn more about LINQ,

I have written code in sql server which I placed a column with a number of identity with OVER PARTITION BY formulation and dive in groups of 6 records like the example below
i j rn color
0 2 1 AMARILLO
0 4 2 AZUL
0 6 3 MARRON
0 8 4 NEGRO
0 10 5 ROJO
1 2 6 VERDE
1 4 1 AMARILLO
1 6 2 AZUL
1 8 3 MARRON
1 10 4 NEGRO
2 2 5 ROJO
2 4 6 VERDE
2 6 1 AMARILLO
2 8 2 AZUL
2 10 3 MARRON

so i want to translate this code made it in sql to LINQ. how can i do that?

here's my sql

WITH T1 AS (
SELECT [i],[j],ROW_NUMBER() OVER(ORDER BY [i],[j]) AS RANGO
FROM (
		SELECT [Row]
      ,		   [Col]
  FROM [ROAMING].[dbo].[Filas_Columnas]
	  )  AS T([i],[j])),
T2 AS (
			SELECT color,Id
			FROM (
			SELECT COLOR,Id FROM COLORES)  
			AS T(color,Id))
SELECT
	A.[i],A.[j],A.rn--,B.color--,B.rn
FROM
	(
	SELECT [i],[j],RANGO, ROW_NUMBER() OVER(PARTITION BY ((RANGO - 1) / 6) ORDER BY RANGO) AS rn
	FROM T1
	) AS A
	INNER JOIN
	(
	SELECT color, Id AS rn
	FROM T2
	) AS B
	ON A.rn = B.rn
ORDER BY
	A.[i],A.[j]

I was trying to do this example but I did not get the result
