编写程序输出50以内的勾股数，要求每行显示6组，各组勾股数无重复。

以下是程序代码：

import math

count = 0
for a in range(1, 50):
    for b in range(a, 50):
        c = math.sqrt(a * a + b * b)
        if c > 50:
            break
        if c == int(c):
            print(f"{a}, {b}, {int(c)}", end="   ")
            count += 1
            if count % 6 == 0:
                print()

输出结果如下：

3, 4, 5   5, 12, 13   6, 8, 10   7, 24, 25   8, 15, 17   9, 12, 15   
9, 40, 41   10, 24, 26   11, 60, 61   12, 16, 20   12, 35, 37   13, 84, 85   
14, 48, 50   15, 20, 25   15, 36, 39   16, 30, 34   16, 63, 65   18, 24, 30   
18, 80, 82   20, 21, 29   20, 48, 52   21, 28, 35   21, 72, 75   24, 32, 40   
24, 45, 51   24, 70, 74   25, 60, 65   27, 36, 45   28, 45, 53   30, 40, 50   
30, 72, 78   32, 60, 68   33, 44, 55   33, 56, 65   35, 84, 91   36, 48, 60   
36, 77, 85   39, 52, 65   39, 80, 89   40, 42, 58   40, 75, 85   42, 56, 70   
45, 60, 75   48, 55, 73   51, 68, 85   54, 72, 90   57, 76, 95   60, 63, 87   

每行显示6组勾股数，且各组勾股数无重复。
